The MEGGER DUCTER DLRO-10 brings new standards to low resistance measurement. It's fully automatic instruments, selecting the most suitable test current, up to 10 A dc to measure resistance from 0.1 µΩ to 2000 Ω on one of seven ranges.

The Megger DLRO-10 Ducter Digital Low Resistance Ohmmeter is built into a strong, lightweight case that is equally at home in the field or in the laboratory. Light enough to be worn around the neck, they are small enough to be taken into areas which were previously too small to access. DLRO 10 uses a large, bright 4-1/2-digit LED display.Normally, measurements are made with forward and reverse currents to cancel the effects of any standing voltages across the test sample.

The instrument is supplied as standard with a Nickel Metal Hydride (NiMH) battery pack. The battery packs are inter- changeable so that an exhausted battery may be recharged using the external charger supplied while testing continues using a spare pack. Although full charging will take 4 hours, a fast charge mode allows the battery to be 90% charged within 2 1/2 hours from a 12 volt battery or from a standard 120/230 V AC supply via the supplied charger. The battery pack contains its own battery state indicator, which allows the charge-state to be monitored, even without being connected to the instrument.

To assist operator safety and ease of use, both instruments are supplied complete with a pair of duplex handspikes with 1.2 m (4 ft) leads. One of the probes is fitted with LED’s, which duplicate indicators on the instrument display indicating that all four contacts have been made, the presence of a high voltage across the load, and the presence of current flow while a load is discharging. A full range of test leads is available with probes, clamps and Kelvin clips.

Applications

The needs for accurate low resistance measurement are well known and very diverse. They range through Goods Receiving inspection of components to ground bonding and welded joints. Typical applications include, but are not limited to, making d.c. resistance measurements of:
  • Switch and contact breaker resistancen Busbar and cable joints
  • Aircraft frame bonds and static control circuits
  • Integrity of welded jointsn Inter-cell connections on battery systems up to 600 V peak
  • Quality control of resistive components
  • Transformer and motor winding resistancen Rail and pipe bonds
  • Metal alloys, welds and fuse resistance
  • Graphite electrodes and other composites
